About Interstate 4
Stretching 132 miles across central Florida from Tampa to Daytona Beach, I-4 is one of the most heavily traveled highways in Florida. It passes through the Orlando tourist corridor where gas station prices often reflect the high tourist demand.
A 2-mile detour to save 20 cents per gallon on a 15-gallon fill-up saves $3. With a car getting 28 MPG, the detour uses 0.14 gallons. Detours above 3-4 miles for savings under 20 cents per gallon are generally not worthwhile.
The cheapest gas along Interstate 4 is generally found in Florida, where lower fuel taxes and proximity to refineries or pipelines keep prices down. Avoid fueling at highway-exit stations in Florida, where tourist premiums push prices 15-25 cents above the best nearby rates.
For a trip along Interstate 4, a vehicle averaging 25 MPG would use approximately 1 gallon per 25 miles. At current average prices along the route, budget approximately {perMileCost} cents per mile for fuel. Plan fill-ups in lower-price states whenever possible.
Yes — consistently. Highway-exit gas stations charge 10-25 cents more per gallon than stations just 1-2 miles off the interstate. Whenever possible, exit the highway and drive to a commercial area for competitively priced fuel.
